Working closely with stakeholders, a comprehensive BIM Implementation Roadmap was developed to align owners, consultants, and contractors through an integrated construction information management framework. The scope included the development of tailored BIM standard documents and the delivery of targeted training to ensure stakeholders clearly understood the client’s BIM vision, roadmap, documentation, and digital platforms—laying the foundation for consistent, scalable BIM adoption across the portfolio.

Supporting the client’s design of the superstructure, roof and façade systems, we provided structural modelling and documentation services. Using MicroStation, we delivered a full set of reinforced concrete construction drawings. BIM services included developing 3D models in Revit and Tekla to resolve clashes and reinforcement congestion within the complex structural forms. We also assisted with reinforcement calculations for columns, beams and slabs using the client’s Robot analysis model, helping ensure buildable, high-quality outcomes within budget and tolerance constraints.

Developed from 2D CAD information, the integrated Revit model was produced by a multidisciplinary team within a four-week programme, resolving clashes and construction challenges as the design progressed.

The coordinated BIM models were used by the main contractor during construction, while a millimetre-accurate point cloud survey informed a data-rich as-built model for digital walk-throughs and ongoing asset management. In parallel, we provided BIM training to AAHK teams in Hong Kong and Vietnam, helping build internal capability for the wider Three Runway System expansion programme.

Our scope of work involved multidisciplinary as-built LOD 350 – 500 BIM modelling for 700,000 m² of existing buildings, including the Terminal 1 main building, link bridges, aircraft loading bridges, ground transportation centre, limousine lounge and associated tunnels, north satellite concourse and skypier.

To create the as-built BIM model, the Airport Authority provided us with thousands of pieces of reference information such as as-built architectural, structural and building services drawings, photos, data schedules, point cloud and panoramic photos.

From the reference information, we created a fully federated LOD 500 as-built BIM model, incorporating architectural, structural, building services, Special Airport Systems, and associated civil/underground utilities.

During the 2-year programme our team validated over 10,000 folders, 500,000 files and 391GB of information, and created and aligned over 3,000,000 BIM geometries.

Atlas is one of few companies in the world with the expertise and capacity to take on such a large project and deliver it to the aggressive programme. We mobilised a large multidisciplinary team to fully model the terminal building in the first 3-months to meet programme requirements. We then continued with model validation against point cloud files and asset tagging.

The project formed part of a broader hotel rebranding programme and focused on the renovation of a prestigious hotel bar.

Coordinated LOD 300 BIM models were produced for MEPF services, supporting design integration and efficient project delivery.

In addition, we delivered targeted training for internal stakeholders and external consultants, ensuring consistent adoption of BIM management processes across the project portfolio.

Achieving this required a coordinated BIM model capable of detecting clashes, supporting construction sequencing, and informing safety assessments. The client also needed clear, ongoing coordination across disciplines and a robust approach to maintaining and updating project information.

We provided comprehensive BIM and documentation from LOD 200 to LOD 400 in critical areas supported by integrated civil and structural engineering expertise.

From existing design information, we produced a fully integrated BIM model with particular focus on the viaduct’s critical interfaces with live transport infrastructure. We confirmed the accuracy of the design work, detected clashes and confirmed that the design was buildable. Throughout the project, the model was rigorously maintained and updated. In addition, we supported the design and planning of temporary works and contributed to improvements in the buildability of the permanent works.

One of our team members worked from the client’s project office, enabling close day-to-day coordination with the wider project team, additionally helping support the development of construction programmes, detailed modelling of construction sequencing, and the assessment of health and safety considerations.

At project completion, the Project Director could demonstrate to their Board that collaborating with Atlas contributed to a direct project saving of close to HK$20million.

Our MEP team developed new LOD 300 BIM models for all building services from the ground up, using the supplied as-built information and aligning all outputs with the client’s BIM Standards. To meet the programme, we deployed a dedicated team: six engineers and technicians to model the first data centre over six weeks, and four specialists to deliver the second building over eight weeks. This provided the client with accurate, fully digitised MEP models to support their ongoing asset management.
